Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Justice in divided societies: the role of competing narratives in Sri Lanka’s transitional justice landscape

open access: yesThe South Asianist, 2017
This paper explores the contested nature of truth and memory in Sri Lanka’s transitional justice debate. It delves into the predominant Sinhalese and Tamil narratives that present opposing demands for justice in the aftermath of the armed conflict.

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

open access: yesAdvanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion

A “Cool” Route to Battery Electrode Material Recovery

open access: yesAdvanced Energy Materials, EarlyView.
Ice‐stripping, a novel sub‐zero electrode delamination technique, enables >90% recovery of the electrode materials from manufacturing scrap and end‐of‐life batteries. Water is sprayed upon a porous electrode and quickly freezes when placed on a cold surface. The foil is peeled away, leaving behind the black mass with the morphology retained.

Elucidating the Impact of Functional Additives on the Structure and Ion Dynamics of Hybrid Solid Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Using multinuclear and multiscale solid‐state NMR, the bulk and interfacial structures of a LiI‐integrated PEO‐LiTFSI‐Li6PS5Cl hybrid solid electrolytes are elucidated, revealing LiI's dual role in enhancing bulk Li‐ion mobility and facilitating Li‐ion diffusion across the organic/inorganic interfaces.
